Salihovic has about three qualities that are world-class - crossing, shooting, and free-kicks. The rest, fairly average to good. All in all, that means he can get his assists (from his crosses), he can chip in a goal if he gets it in a good place,(good hard shots) and he is deadly from dead-ball situations. But, he's isn't a player that can carry and dictate play, nor does he generally make his teammates much better (his team-mates do as much for him as he for them - so it cancels out)
Miske on the other hand has the ability to carry the play and generally dictate play. His passing, vision, intelligence are world-class imo, and many others things are good to very good, and for a play-maker, that's lethal. He also clearly makes his team-mates better and raises their game, whether it be making a smart play, putting the ball in good positions, or doing the difficult stuff and leaving the simple things to the less skilled guys.
He basically does everything.
I actually disagree with that. I think you may be referring to the Salihovic last season. From what I've seen in the games such as against Bayern, Turkey, and Gladbach...he was everywhere on the field....left, right, top, back defending, in the middle distributing the ball from defense to attack...
I mean have you seen the game against Turkey or against Bayern? According to stats, he had the most passes in each of those games and I've watched both games full 90 mins each. Today he turned around the game against Gladbach from 2-0 to 2-2 and pushed up front for the 2-3 and 2-4. He's great both defensively and offensively. I don't think Misimovic has the defensive capabilities, or the strength and speed Salihovic has.
PS: Adnan, you have no idea what you're talking about. Dzeko has been poor since game 1 till now in the bundesliga... and he was the worst player on the field against both Armenia and Turkey, what do you have to say about him? And by your concept, Pjanic is already better than Salihovic.
